PROCESS HEAT

WORLD OIL PRODUCTION

Decline in oil production is already underway

SOLAR INTEGRATION WITH EXISTING

SYSTEMS

Solar Heating systems should be integrated with existing systems already in operation

with the primary aim of reducing the total cost of operation. Solar Heating may not

provide all heat required for the process due to lack of space or seasonal variation in

solar radiation.

APPLICATIONS IN USE

KNOWN APPLICATIONS

1.Boiler Feedwater Pre-heating

2.Dairy Processing

3.Community Cooking

4.Solar Cooling

BOILER FEEDWATER PREHEATINGSolar water heaters can be used for pre-heating boiler feed

water or makeup water to 70-85 deg C and can have an

ROI within 2 years.

SOLAR COOKING

Scheffler Dishes have been for more than a decade for large

scale community cooking.

DAIRY PROCESSING

Multiple processes in Dairy require heat – Pasteurization, Cream

Pasteurizer, Ghee Melting, Powder or Khova (Mava) production

SOLAR COOLING

Adsorption and Absorption chiller can be used with hot

water generated from solar field to produce chilled water to

operate HVAC equipment.

1.Steel Mould Pre-Heating

2.Bitumen & Aggregates Heating2.Bitumen & Aggregates Heating

3.Industrial Effluent Drying

4.Hydrogen Production

STEEL MOULD PRE-HEATINGMoulds are heated using air to maintain them at

120-150 deg C when on conveyor and heat them

to 300 deg C before the molten steel is poured.

Molten Steel is poured in a mould

STEEL MOULD PRE-HEATING

Air is heated using electrical heater

banks placed in the air supply ducts.

Hot oil heating by Solar Concentrators can

be circulated in heat exchangers like this to

generate the same hot air

BITUMEN HEATING

Process involves heating Bitumen, Aggregates & Reclaimed Asphalt (if available).

BITUMEN HEATING

Diesel is used to heat bitumen before sending it to mixing tank.

The temperature required for mixing is 150 deg C-160 deg C.

BITUMEN HEATING

Simulation results show a high solar fraction of 83.7% , saving

significant fossil fuel.

AGGREGATES HEATING

Rock aggregates are also

used in road laying and

typically involving burning of

diesel to heat them before

mixing with Bitumen. Air at a

super-heated 160°C or vapor super-heated 160°C or vapor

steam at up to 300°C is used

for heating.

Solar heating can be used

(with conventional backup) for

this purpose greatly reducing

the cost of road laying.

INDUSTRIAL EFFLUENT DRYINGIndustrial effluent drying is required for two reasons:a) High cost of transport to landfillb) Restrictions on effluent discharge & Zero Liquid Discharge policies

Using Solar Green House is one way of doing effluent drying as shown below:

INDUSTRIAL EFFLUENT DRYING

Industrial

effluent can

also be dried

using Multi

Effect

Evaporators

(MEE) where (MEE) where

steam is used

to recover water

from the

effluent.

Steam required

for MEE can be

produced using

Solar

Concentrators

HYDROGEN PRODUCTION

To usher into a Hydrogen economy, Hydrogen needs to be

produced at an optimal cost. Ultra high solar concentration can be

used for Hydrogen production using Metal-oxide reactions.
